Notes on Pin Description:
1. The PLA[5:0] and PLD[3:0] ground pins are not internally connected together.
Failure to connect these pins externally may cause malfunction or damage
the device. The PHA[4:0] and PHD[3:0] power pins are not internally
connected together. Failure to connect these pins externally may cause
malfunction or damage the device.
These power supply connections must
all be utilized and must all connect to a common +5 V or ground rail, as
appropriate.
2. Inputs MENB, RSTB and ALE have integral pull-up resistors.
3. All outputs have 2 mA drive capability except for MRD and the D[7:0]
bidirectionals which have 4 mA drive capability.
4. All inputs and bidirectionals present minimum capacitive loading and operate
at TTL logic levels.
5. The TDLSIG/TDLINT[4:1] pins have integral pull-up resistors and default to
being inputs after a reset.
